Parameter Comparison

Engineering Selection Recommendations

Both the ARJ11C-MASAB-B-A-1MU2 and A63-113-213N491 are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component deployment. The substitute part A63-113-213N491 maintains functional equivalence across all critical electrical and mechanical parameters specified for 10/100 Base-T Ethernet applications.

The A63-113-213N491 demonstrates higher contact finish thickness (15.0µin versus 6.00µin), which may provide extended contact durability in high-cycle insertion applications. Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Selection between these parts should be based on availability, lead time requirements, and procurement cost considerations, as both meet the specified application requirements.

Frequently Asked Questions (FAQ)

Q: Can A63-113-213N491 be used as a direct replacement for ARJ11C-MASAB-B-A-1MU2?

A: Yes. Both connectors meet equivalent specifications for RJ45 1-port through-hole solder termination with 90° right-angle orientation, 10/100 Base-T AutoMDIX capability, shielded EMI finger design, and board lock features. Operating temperature range, contact finish material, and regulatory compliance are identical.

Q: What is the difference in height above board between these parts?

A: The ARJ11C-MASAB-B-A-1MU2 has a height of 0.535" (14.69mm), while the A63-113-213N491 measures 0.530" (13.45mm). This 0.005" (0.14mm) difference is within typical PCB layout tolerances for through-hole connector applications.

Q: Are there differences in contact finish specifications?

A: The ARJ11C-MASAB-B-A-1MU2 specifies 6.00µin (0.152µm) contact finish thickness, while the A63-113-213N491 specifies 15.0µin (0.38µm). Both use gold contact finish. The thicker finish on the substitute part may provide enhanced contact durability in applications with frequent mating cycles.

Q: Do both parts have the same MSL rating?

A: Yes. Both the ARJ11C-MASAB-B-A-1MU2 and A63-113-213N491 are rated MSL 1 (Unlimited), indicating no moisture sensitivity requirements during storage, handling, or assembly processes.

Q: Are regulatory certifications equivalent?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, classified as EAR99 for export control purposes, and share the same HTSUS code (8536.69.4040).
